Swallowing semen to encourage labor WTH?!?!

And I was reading up nonmedical ways to induce labor since everyone on here has been getting me thinking about it. And get this... here I'll quote

"A man's semen contains prostaglandins, hormones known to start labor that, in their synthetic form,are sometimes used for medical inducitons. Intercourse delivers these hormones to the cervix, but in some cicles, it is thought that oral sex involving swallowing the ejaculate is more effective.".. pg 271

Lol, what "circles" are these. They wouldn't be completly hosted by men would they? Ha! Who writes this stuff anyway?

Lol! I also read that swallowing semen is supposed to help with morning sickness. That is THE VERY LAST THING I would want to do when I'm nauseous! And yes, it was a male that published this "study." Crazy what men will do to get a piece :-)
